Sans AUs Fighter 2 is a Roblox fighting game where you battle as the many Sans characters from Undertale and its fan-made AUs, earning EXP and Gold to unlock stronger fighters. EXP is what levels you up and unlocks new characters, while Gold is the premium currency, and grinding both through fights alone takes a while. That is where codes come in, since they hand you free EXP and Gold with no grind attached. Stacking the active ones gives you a real head start on your next Sans.
Sans AUs Fighter 2 codes are released by the developer around updates, milestones, and events, and they reward either EXP or Gold. Redeeming is quick: open the Codes button on the left of the screen, type a code into the box, and hit Submit. The codes are case-sensitive, so the easiest way to redeem them is to copy each one straight from the list below, and we add new ones here the moment they are confirmed working.

🎮 How To Redeem Codes in Sans AUs Fighter 2
- Open Sans AUs Fighter 2 on Roblox and wait until you have spawned in.
- Find and click the Codes button on the left of the screen.
- Type or paste a code into the text box exactly as it appears here.
- Click the green Submit button to claim it.
- Your EXP or Gold is added to your account right away.
Codes are case-sensitive, so copy them straight from this page with the Copy button to avoid typos. If a brand-new code says invalid, hop to a fresh server, since older servers can run an earlier version of the game.
When Do New Sans AUs Fighter 2 Codes Drop?
New Sans AUs Fighter 2 codes usually arrive with big updates, new Sans reworks, and visit or like milestones, which is why so many past ones were named after them, like 3MVisits and 10kLikes, or after events and apologies for downtime, like thanksgiving2025 and SorryForDataDebugging. New codes are not always announced inside the game, so they tend to show up around each update and event. Check back here after each patch, since we add new codes as soon as they are confirmed working.
🎮 About Sans AUs Fighter 2
Sans AUs Fighter 2 is a Roblox fighting game by the group yuika shenanigans, inspired by Undertale and its many fanmade AUs. You play as the Sans characters from those alternate universes and fight bosses, training dummies, and other players to earn EXP. You then spend EXP and Gold to unlock stronger Sans fighters and new movesets, and matches run on 15-player servers with a bonus to EXP in public ones.
Because EXP and Gold are what gate your next Sans and moveset, codes are the fastest way to grow your roster without grinding. Redeem the active ones early and you start out with a stack of EXP and Gold that would otherwise take real playtime to earn. New codes tend to follow each update and event, so it is worth checking back here whenever the game gets a fresh patch. Note that the game carries an epilepsy warning for its flashing lights, so take care before you jump in.
